Material Properties

Duplex 2205 stainless steel (UNS S31803/S32205) offers exceptional corrosion resistance combined with high strength. This nitrogen-enhanced grade provides superior performance compared to standard austenitic stainless steels.

Key Benefits

High resistance to pitting and crevice corrosion
Excellent performance in most caustic environments
Superior weldability characteristics
Enhanced strength-to-weight ratio

Note: Not recommended for use above 300°C (brittle precipitation) or below -50°C (ductile-to-brittle transition).
